Display Mode
This character shows the currently selected display mode:
Bar-graph mode displays twenty four channels as a bar-graph with a resolution
of 12,5%. Whilst the resolution of this mode is limited, it is often the most useful
when the DMX line is running show information. It is easy to pick out chases,
which in other display modes could be mistaken for flickering data.
DDecimal mode displays six channels as numbers in the range 0 to 255.
This mode shows the entire resolution of each channel. It is most useful when
dealing with moving lights and colour changers.
%Percent mode displays six channels as numbers in the range 0 to 100.
This mode provides the most familiar numbering system.
$Hexadecimal mode displays six channels as numbers in the range 00 to FF.
This mode is most useful when working with DMX devices such as relay boxes
and smoke machines, which use bit control. See Appendix for conversion tables.
Data Received Indicator
This character cell displays a tilde to show that data is being received.
The data is not necessarily valid DMX512.
Data Error Indicator
This character cell is clear when good data is being received. If an error occurs, one of
the following is displayed:
HDMX512 is being received with a non matching Header or stars code.
FData is being received with Framing errors. This can be caused by noise pick-up
and also occurs when the phase pins of the connector are reversed.
OData is being received with Overrun errors. This can be caused by noise pick-up
and also occurs when a phase pin is disconnected.
TThe received data is outside the DMX512 Timing specification. This display
occurs when either the number of channels per frame exceeds 512, or the Break
time is less than 88uS, or the MaB time is less than 4uS.
Loop Through Indicator
This character cell displays 'L' when Micro-Scope's output is providing a
clean and buffered version of the incoming DMX512. When the character cell is clear,
Micro-Scope's DMX512 generator is connected to the output.
